http://www.physorg.com/news108988221.html a great leap forward...but not completely without precedent. Vicinal surfaces have been used for nanograting structures before. If nature picks it, must be right.

...however it seems nature allows some
line edge roughness in this case.

I think self-assembly is best-suited for applications which just involve depositing films with special properties (e.g., photonic crystals, superlattices,etc), rather than directly making fine lines and such.

The pictures do no justice to reality. The self-assembled lines are much wavier on a larger scale.

Maybe after zooming out, it doesn't look so marketable...need to get and read the article (subscription needed).

Self-assembly is like biology. Very cost effective but also very prone to mistakes and defects.
